(I have cut out a section where it tries to write it to a doc file. (just the writting))What I was wondering is how would I improve several parts of this code?
1. The speed - Already In a background worker (I will write a delegate soon )
2. The chars that can be used with it because this only allows the preset ones I would like to be able to use other ones like � or Chinese chars etc.
I am trying to use string.format on a url to pass several values into the string. It's probably a simple error but I cannot get the following code to work. It doesn't even build the string.
Public Sub getStockData() Dim client As New WebClient() Dim url As String
What would be the fasted method of get a string list of all values within [] in a string of text? For example: [client_name], are you are doing today? My name is [my_name]. The list of strings would be:
I have tried just about every format I have found, and I can not seem to get the string digits 0-9 to show up as "00 - 09". Now I do not want numbers 10+ to show up as 010, 011, etc. I also know there are (2) ways to format strings as well:Microsoft.VisualBasic.FormatandString.FormatI have tried all of the following with no[code]...
I doing a project for my office. In that I am showing the values and strings from a particular table based on the date range and vendor selection. It is working fine with the date range. Except within the date range if the particular reader has no data it throws an error message like dbnull string.
Lets say I have a string that could look like this[code]...
I want to break each of those in to two strings. The break point would be two decimal places to the left of the existing decimal point. So in the first example I would end up with 123 and 07.37 and the second example I would end up with 44 and 01.0. I assume I need to use a form of .indexof("."), but I cant figure it out.
How can i compare two string values in vb.net? i've tried compare, equals functions but it's not giving me the correct result. what i'm trying to compare is as follows. also let me know if the code is correct. i'm new to vb.net
I have a Data Connection set to my Access file. I an connect fine and run queries and whatnot. When I close VB 2008 and re-open the project it won't connect to the Database again. It loses the password for my Workspace for some reason. There is no option to save the password, but it doesn't lose any of the other information in the connection string.
Using VB.Net, I need to read the following XML from a string variable (not a file) and pull the AuthNo, Client ID, Client Name, Supplier ID, and Supplier Name for each Dispatch contained within the XML.
I have looked at tons of examples on the web using XMLReader but I can't figure out how to pull the separate ID's and match them up with their appropriate Names and also matched up with appropriate AuthNo.[code]...
is my string that return the value, dim strID as string="2343-dsds3-65gff".if the values in all the strID are zero,i.e.,strID as string="0000-00000-00000". i want to display error.
I am trying to verify that a string contains nothing but known values. In this case, I need to make sure it contains only "Shift", "Control", or "Alt", but not necessarily all of those. For example, these should be true: "Shift + P", "Shift + Control + H", "Alt + U; but these should not: "Other + P", "Shift + Fake + Y", "Unknown + Shift + E" etc.This is the code I tried to use:
If Not shortcut.Contains("Shift") Or Not shortcut.Contains("Control") Or Not shortcut.Contains("Alt") Then MessageBox.Show("Invalid") End If
I'm having difficulty wrapping my head around the needed logic to do this. I'm assuming there's a logic operator that can do this?
Looking for the simplest way to extract values from a string. For example consider the following:Dim args As String = "/firstname:Bob /lastname:Jones"..To simplify, I need to be able to popup a box that says "Firstname = Bob" or "Lastname = Jones"
I am very new to VB, and am programming in VB 2008 express. Sorry if this thread is in the wrong spot I need to add two 40 digit numbers together and was thinking that the simplest way to do it would be to input them as a string and then convert the string to a single dimensional array where x(1) is the 1st digit in the number, and x(30) is the 30th digit, etc. I would do the same for the other number where y(1) is the 1st digit. I would then add the x(40) and y(40) (which are the last digits of the number) together and carry the remainder into the next addition (39th digit, 38, ...)
I have a tblVersion that contains the versions of my application:
VersionID Version
VersionID is a bigint primary key, version is a ntext column that holds the current version... I want to be able to pick the row that has the highest version number, but version could be in this format:
MyApplication 1.0.1
If I try to convert that to a int32 it will throw an exception obviously. I would like to know if some of you have a idea how to solve this issue. I could of course make sure the column will only contain numeric values but this gives a little more flexibility.
This code I converted VB to C#. But i need to know how can use Hex in c# private string ConvertStringToHex(string sText) { int lCount; string sHex; string sResult; for (lCount = 1; (lCount <= sText.Length); lCount++) { [Code] .....
I have a ListView control set up in details mode, and on a button press I would like to retrieve all column values from that row in the ListView.This is my code so far:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _
I need some thought input on how I can take my string of HEX values and convert them to ASCII according to the specifications below: A function would be ideal since I need to quickly decode about 250 records all having 20 thresholds to record.[code]
I have a simple query but I am just not able to get it right. Have a look at my sample code below:
Sub Function1 My Code Here Function2(Year,Month) End Sub Sub Function2(Year,Month) Dim Str as String() for 1 to 30 Dim MyDate As New Date(Year, Month, i) Str = MyDate.DayOfWeek.ToString() Next Return Str End Sub
I am having a string in CSV format.http:[code].....I can add new values to it by some mechanism. Everything will be same except the new values will have numeric part = 0. Take example I have this exsiting CSV string
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt
Now by some mechanism i added two more files Superman.txt and Spiderman.txt to the existing string. Now it became
What i am doing here is that this csv string is paased into SP where its splitted and inserted to db. So for inserting I have to take the files with numeric part 0 only rest will be omiited .Which will be further then converted into CSV string.Array will look like this
